ABSTRACT:
A method is provided for recording video information in which copy control information of video information is managed in the case of copying the content of data from one recording medium to another recording medium. Copy control information (CCI) or a watermark (WM) of an inputted AV stream is detected and whether the content of the copy control information or watermark has changed is determined. Change point information of the copy control information or watermark and the content of the copy control information or watermark are acquired, and management information for managing the copy control information is generated on the basis of the acquired change point information. The generated management information is recorded together with the video information to a recording medium at a copy destination.
